Seems like former JP model Mio Kudo will join the cast of the ghost hunting band from the Kamen Rider Ghost TV series as a semi-regular one.
This news was recently announced and her role is still unknown as of this writing but with the recent magazine scans featuring Makoto Fukami's (Kamen Rider Specter) background, we can assume that she will portray the role his sister's soul that is trapped inside an Eyecon that talks.
